For his YouTube channel Undecided with Matt Ferrell, the renewables youtuber goes for a deep dive of the latest and upcoming developments in perovskites and tandem solar cells:
Photovoltaic modules based on perovskite silicon tandem solar cells have the potential to achieve higher efficiencies than today's silicon modules. A research team at Fraunhofer ISE has now produced a module with an efficiency of 25 per cent using perovskite silicon tandem solar cells from Oxford PV.
The efficiency was confirmed by Fraunhofer ISE. The cell was manufactured at the factory in Brandenburg an der Havel, eastern Germany. There, Oxford PV is researching new types of perovskite stack cells.
The tandem of silicon solar cell and a layer of metal halide semiconductor already achieves high efficiencies in the laboratory. This efficiency is now to be transferred to mass production.
A study has evaluated the environmental impact of industrially manufactured perovskite-on-silicon tandem solar modules over their entire service life. Result: The tandem solar modules are even more environmentally friendly than conventional silicon heterojunction modules.
Researchers in Berlin have achieved an efficiency of 29.8 per cent with a tandem cell made of silicon and perovskite. Among other things, they have improved the boundary layers between the semiconductors.
A perovskite solar cell of Oxford PV has set a new record for the amount of the sun’s energy that can be converted into electricity by a single solar cell.
Professor Henry Snaith, Oxford PV’s Co-Founder and Chief Scientific Officer, has received the Becquerel Prize in honour of his significant contributions to the use of perovskite in solar cells.
